Does the flashing happen all the time?
The problem with the historic battles is a lot of them are set up to use the original RTW models which have been replaced.
There is no reason why you can't set up your own battle!
Here's how to do it.
I need to thank Annallein and Tony83 from the RTR team for providing this information. I have even nicked the example from one that Annallein posted in the dev forum - which I cannot link you to.
1) Find a location on the strategy map. Put your cursor over the area. Open the 'Rome Console' and type in show_cursorstat. This will bring up some co-ordinates - it is these that you want. Write them down and put them somewhere safe.
2) Close the game down
3) Edit the custom_battles.txt file (I presume this is in the PE\data folder.
Note: with all editing you may want to take a copy of the file before you make any changes.
Here is an entry explaining a custom battle location: (Red=Parameters which you need to change | Green = Comments for explaining)
Code:
custom_location Name This will appear on screen - no need for a text file
{
location x y Coordinates from the Strat(Campaign) map which you can find like the resource coords.
image Image Location and Name You'll need to save the image in .tga. Image size: 256x152 pixels
sett_locked yes/no Wether the CB location should be have a settlement on it and no option to remove it
summer yes/no Wether the wether of the battle should be looked to summer only
}
And an example of how it could look:
Code:
custom_location Pyrenees
{
location 56 69
image TIC/data/menu/CB_pyrenees1.tga
sett_locked no
summer no
}
I've yet to create a TGA for a custom battle location that I have set up. It isn't that important for this. Just pinch an existing one.
